If you know the size of the foreign objects, you can use a shape
attribute (use pango_attr_shape_new()) to tell Pango the size of the
object.

I use the Unicode OBJECT REPLACEMENT CHARACTER, U+FFFC, as the "text"
for external graphics, but you could presumably use some identifying
string if Pango isn't going to do anything with the "text" that has a
shape attribute.

Pango 1.2, AFAICT, doesn't provide any hooks for calling alternative
renderers when it gets to rendering foriegn objects, so I can't tell
you how to do that step.
